Abstract
Disclosed is a chemical administrator which delivers a chemical solution into a water supply line for a water-consuming device, e.g., a toilet in a recreational vehicle, for the purpose of treating waste-water before it is disposed in a holding tank. The apparatus has a container which holds the chemical solution. It also has a chemical administering system which siphons the chemical from the container into the water supply line using a vacuum created by the water moving through it.
Claims10
A chemical dispensing apparatus for delivery of a fluid chemical into a water supply line for a water-consuming wastewater treatment device, the apparatus comprising:
- a set of three interchangeable containers for holding the fluid chemical;
- and
- a chemical administering system adapted to vacuum the fluid chemical from one of the three containers into the water supply line for the water-consuming wastewater treatment device, wherein the water-consuming wastewater treatment device stores a mixture of the fluid chemical and water delivered by the water supply line;
- wherein each of the three interchangeable containers includes a differently sized tube, each tube being adapted to provide a flow path delivering the fluid chemical into the water supply line and to restrict a flow of the chemical, and
- the three tubes being configured with diameters sized to allow for a concentration of one-half ounce of chemical per gallon water, one-third ounce of chemical per gallon water, and one-quarter ounce of chemical per gallon water, respectively, thereby controlling the amount of chemical administered into the water supply line.
A method of dispensing a fluid chemical into a water-consuming device for the purpose of treating waste-water, the method comprising:
- storing the fluid chemical in one of a set of three containers, wherein each of the three containers accommodates one of three differently sized tubes having diameters sized to allow for metering of a concentration of one-half ounce of the fluid chemical per gallon water, one-third ounce of the fluid chemical per gallon water, and one-quarter ounce of the fluid chemical per gallon water, respectively;
- controlling a chemical consumption rate by the following procedure:
- (a) installing one of the three containers to a chemical administering system adapted to vacuum the fluid chemical from the installed container into the water supply line for the water-consuming device, wherein the installed tube accommodates a subject tube of the three tubes;
- and
- (b) interposing the subject tube into a chemical flow path which leads into the water supply line;
- and
- delivering the fluid chemical into the water supply line, which feeds into the water-consuming device, by drawing the fluid chemical out of the installed container via the subject tube using a vacuum created by a pressurized flow of water in the water supply line.
A chemical dispensing apparatus for delivery of a fluid chemical into a water supply line for a water-consuming wastewater treatment device, the apparatus comprising:
- a set of three interchangeable containers for holding the fluid chemical;
- a chemical administering system adapted to generate a vacuum that pulls the fluid chemical from one container of the set of the three containers that is releasably attached to the chemical administering system, wherein the vacuum pulls the fluid chemical into the water supply line for the water-consuming wastewater treatment device, wherein the water-consuming wastewater treatment device stores a mixture of the fluid chemical and water delivered by the water supply line;
- and
- a metering system for controlling the amount of fluid chemical administered into the water supply line,
- wherein the metering system comprises three differently sized tubes, each of these being housed by a respective container, of the three containers,
- wherein the tubes individually provide a flow path of the fluid chemical into the water supply line and controllably restrict a flow of the fluid chemical when the vacuum is applied, and
- wherein the tubes are each sized to allow for a concentration of one-half ounce of the fluid chemical per gallon water, one-third ounce of the fluid chemical per gallon water, and one-quarter ounce of the fluid chemical per gallon water, respectively.
